Today's question: I hear a lot of conflicting reports about whether LNG is safe. How do I know what to believe?
Answer: It's true that there have been some Yukoners expressing concern about the safety of LNG. I think that much of the fear here in the territory stems from a lack of familiarity with LNG. Most of us use hydrocarbon fuels in our daily lives...gasoline or diesel in our vehicles, propane and oil in our homes, and we rarely if ever consider the safety of these fuels. Natural gas is new to Yukon, and so people, rightly so, question its safety.
The reality is that all these fuels have their own unique hazards and need to be respected. As long as all the appropriate safety measures are taken, we can use these products very safely.
Consider this: here in Whitehorse we have two propane tank farms, with a total volume of just over 500 liters. That's about equal to our LNG storage volume. There are diesel tanks at the Whitehorse airport and on our existing Whitehorse site, and we have not heard anyone raise safety questions about them. There are propane tanks near the grocery store in the Riverdale subdivision of Whitehorse, near our generating facilities. Again, we have not heard people express safety concerns about these tanks.
It is generally accepted that LNG is a safer fuel than propane. It has a higher ignition temperature, meaning you need a much hotter spark than you do to ignite propane. As well, the storage pressure of propane tanks is higher than that of LNG, making it more prone to explosions. Natural gas is lighter than air so if you did have an LNG leak, it would disperse upwards. Propane sinks downward and sticks around an area.
In a nutshell, we would not be moving to LNG if we did not believe it is safe, and we intend to implement all the appropriate safety measures in the operation of our LNG site. Here is a video that talks more about LNG and safety.

Yukon people are smart, resilient and understand the consequences of their energy choices. That is why when they view this video they will realize just how unsafe LNG is. http://unfccc6.meta-fusion.com/cop20/events/2014-12-06-12-00-abibimman-foundation-arctic-methane-emergency . It is the GHG potency of methane that is it’s greatest danger. Fugitive methane emissions associated with the production of LNG makes diesel a far safer fuel. When YEC says that a LNG leak “would disperse upward” as a safe behaviour does not recognize the potent GHG that methane is unburned. LNG is unsafe ignited as well as unburned. As soon as it is fracked out of the ground it is unsafe. The IPPCC says we have to leave 80% of our fossil fuels in the ground to avoid catastrophic climate change. Now with the most recent findings and the massive methane leaks bubbling out of the Siberian ocean shelf, we need to act now to reduce our emissions. I am still hoping one day that the LNG site will be a solar energy parking lot for electric cars. We could have a memorial park for the trees that were needlessly destroyed and Whitepass and Yukon route could partner with YEC and the city to run a small electric commuter train into town from the solar parking lot.
